You talk to Claude Code like you would any AI assistant. When entering your prompt, here are some things to consider that can both protect you and make things easier.
You can choose how much oversight to keep while Claude works. Press Shift + Tab to cycle between modes.
There's no right or wrong answer — it's whatever you're comfortable with.
Within the Shift + Tab menu is Plan Mode. Plan mode takes your prompt and uses read-only tools to analyze your codebase and research your suggested implementation. It will ask clarifying questions along the way, then return a detailed plan it can execute.
Plan mode is great for planning complex changes or doing a safe code review. Many times you'll be asking Claude to handle multi-step implementations toward a feature, and this is exactly where Plan Mode excels.
Let's walk through an example. Say you have an application that needs a dark mode toggle. Open the root directory of your project and run claude. Press Shift + Tab a couple of times to enter Plan Mode, then write a prompt like:
My app needs a dark mode implemented across the entire app. Can you create a toggle switch on the header that allows a user to toggle between light mode and dark mode? I need you to find a good contrast color that works based on my existing light theme.
Let Claude plan it out. After reviewing the plan, if it looks good, accept it and let Claude work through it — depending on your permission mode, it may check in with you along the way. At the end, you can see exactly what Claude did and how it reached its conclusions.

When using Claude Code, try to be as descriptive as possible with your prompt. If you want to stay in the loop at every step, you can. Use Plan Mode to let Claude dig into the details of what you want to achieve before executing on any code.
